Graeme Anderson

Graeme works on the development of the Met Office lightning locating network (ATDnet) and on GNSS meteorology

Areas of expertise:

  • Meteorology
  • Lightning detection
  • GNSS meteorology

Current activities

Graeme's main area of work is on the development of the Met Office lightning locating network, Arrival Time Differencing network (ATDnet), which locates lightning by measuring the arrival time of the Very Low Frequency (VLF) radio signal (or 'sferic') emitted by lightning strokes to a very high precision, then uses the difference in the arrival time at a number of stations to work out where the lightning occurred. This work involves plotting data and calculating statistics, and coordinating work with companies and institutions who use the data.

Graeme also spends some of his time working on data derived from global navigation satellite systems (GNSSs) such as GPS. The amount of water in the lower atmosphere and the amount of charge in the ionosphere both have an effect on GPS signals, and this effect can be understood and used in order to build maps of atmospheric water content and ionospheric charge.

Graeme has also spent some time working on radiosondes, the instruments that are attached to weather balloons that are vital to observations of the atmosphere.

Career background

Graeme joined the Met Office in 2011 and completed the forecaster training course in the Met Office College, before switching into Observations Research and Development in early 2012. Prior to joining the Met Office, he completed an MSc in Applied Meteorology at the University of Reading, and a BSc in Physics at the University of Edinburgh.
